Lvl 150 focus ring isn't really made for casters
#1I was kinda excited to see the lvl 150 focus ring with 100 focus show up in the shop after the patch. However I got to thinking it is basically useless. I am around lvl 100 and even at my level 100 focus only adds about 30 on to my natures touch. A +1 natures touch ring does better. What actually appeals to me as a druid is resistances and defense so I can survive if I take aggro. And most druids don't need more in combat regen. The moral of the story is the 200 defense ring is more appealing to me as a druid than the lvl 150 caster ring.
A Mage is like a Lamborghini, You don't get one as your first car or daily driver and there are cheaper cars that go faster and are more comfortable anyway.
